Help with rowfun?

I've created a table with columns Go,Export, and Directory and row names from a list of strings (ex {'First Row','Second Row'})
I have a helper function, generic_helper that takes each of a Go, Export, and Directory values from a table, along with the string corresponding to the row (ex 'First Row') and a binary flag that does not change across rows.
How can I apply rowfun to call generic_helper(Go,Export,Directory,rowName,ex_bin_flag) for the values of Go,Export,Directory, and rowName in each row of my table?
Thanks in advance!

You should have the helper function with some output (one or multiple scalars (single values)). Then, in your code you can use
newtable=rowfun(@generic_helper,table);
Note from rowfunc doc: "To return more than one output from func, use the 'NumOutputs' or 'OutputVariableNames' name-value pair arguments."
PS you were correct in looking for a vectorized solution, they are indeed generally faster. For smaller problems the effect is often negligible, but it always affects readability.

Well, then you can either declare bin_flag and rowName as global variables, or create two new global variables in which you paste the content of bin_flag and rowName.
